Clean up/space out/refactor status component

It's very cluttered and compressed at the moment, and the header is a mess that breaks on mobile (hides the reply arrow which is pretty vital to have).

• Need to have more consistent and wider spacing
• Adjust styles in statusnet_html so that linebreaks and different paragraphs have a more similar spacing
• Change the header:
  • top row: <username (cuts off, doesn't wrap)> <the stupid buttons which aren't all buttons>
  • bottom row (if reply): <reply arrow icon maybe, this + text after work as preview trigger> Reply to: <username of other, cut off, don't wrap>
• Make the usernames expand the usercard instead of taking you directly to the user profile page (taking users out of timeline is never a good idea)
